Tyler, Roberto and team have been fantastic. They clearly lay out options, maintenance and best practices while also educating us on the intricacies of our old house. I’d recommend the maintenance plan they offer.

We have had an outstanding relationship with AOK Plumbing, Heating, Cooling since 2008 — flips, rentals, our own residences — this is the sole company that we continue to trust 100 % with our investments. What a satisfying feeling to have this level of confidence in our chosen company! Their workmanship and knowledge of HVAC and plumbing systems is a display of excellence, while they are always courteous, respectful of our properties, and friendly. We proudly recommend none other than AOK to others seeking a positive repair experience.

Great service guys! Always go above and beyond to make sure you’re satisfied, and that the system is running the best it can. Tuned up both my old furnace and an even older AC.

If I could give A-OK 10 stars, I would! After experiencing back-up plumbing issues in my home for over a year AND after having 2 other companies come out and do their thing, of which the 2nd guy totally ripped me off, the problems continued. You can imagine my frustration at having to call, yet another plumber. Finally picked a winner with A-OK. Steve came out, early mind you, listened to my issues and I explained what the past guys had done. Well, I instantly saw the light come on in Steve’s brain, it was beautiful. He went right to work, was done in about an hour, cleaned up after himself and I was actually delighted to pay the bill. Shoot, I kinda wanted to give him a tip! Everything is flowing, flushing and fantastic, with a warranty to boot! He left me an A-OK sticker on my water heater for any future problems and you can best bet, I’ll be referring to that little sticker should the need arise. Thanks, Steve. You rock!
